The steel is hardened to 58 Rockwell. These blades have a slight bend cut in the tube for the steel so that you only need to slightly bend your blades. This means that the tube has less stress and less chance of it losing its bend like normal blades. Features Blade 58 Rockwell Japanese steel 6061 aluminum tube
